Silver metal

Answer 1

Silver metal is a substance because it has a uniform and definite composition. Every piece of silver you have is made up entirely of silver atoms, which gives it the same properties throughout. Unlike mixtures, which can have different proportions of components, silver metal always retains its specific characteristics, such as its color and conductivity.
